**Shafts** are cylindrical mechanical components that transfer torque and rotational movement in machines.They are widely used in a variety of machines from everyday households to industrial equipment. A wide range of different shaft types are used in engineering, each designed to do a specific function and different conditions, to support mechanical power and to allow various machine components to work together. They connect components like gears, pulleys, and wheels to work together. Shafts are classified into **supporting shafts** and **moveable shafts** based on their function. **Moveable Shafts** - These shafts carry components like gears or pulleys that transfer forces and torsional loads. (They carry parts on them, they are put on bearings) - Bearings support these shafts, handling radial and axial forces. - Types of moveable shafts include: - **Driven shafts** - **Layshafts** - **Propeller shafts** **Supporting Shafts** - These shafts don\'t transfer torque but allow rotation in specific areas. - They can either stay still or rotate. Shafts are commonly made from materials like steel for durability and flexibility. They are used in both household devices (e.g., washing machines) and industrial machinery (e.g., lathes). Every type of shaft is designed for a specific purpose but all share the role of transmitting power and motion. **Cars are a good example of using various types of shafts** - **Driveshafts**: Connect the gearbox to the wheels, transmitting power from the engine to move the vehicle. - **Axles**: Support the vehicle's weight and transfer power from the engine to the wheels while rotating with them. - **Camshafts**: Operate to control engine valves, managing the air-fuel mixture and exhaust. In summary, shafts are essential components in machines, enabling power and motion transfer effectively. They must be able to withstand the forces without deforming (**strenth and durability)** Shafts should resist twisting under torque to maintain stability**.(torsional rigidity)** Repeated loading can cause fatigue, so shafts are designed to endure cyclic stresses (**fatigue resistence)**
